It's just google-chrome.
And honestly, the last thing I want to ever see is non-ASCII URL's.
Particularly from a security person. It's a *HORRIBLE* idea with
homoglyphs, and personally I think any browser that refuses to look it
up would be doing the right thing.
But I don't think that it's the browser, actually. Even 'nslookup'
refuses to touch it with
** server can't find א.cc: SERVFAIL
and it seems it's literally the local dns caching (dnsmasq?)

No. It's a bad idea. Full stop. Don't do it.
